Top Causes of an Itchy Scalp

1. Dandruff and Seborrheic Dermatitis: The Most Common Offenders

Those small, flaky white bits that often come with itching are usually dandruff, which is commonly caused by an overproduction of oil or reactions to irritating hair products. The more you scratch, the worse the inflammation tends to get.

Seborrheic dermatitis is a more serious version — a chronic condition marked by red patches and greasy, yellowish flakes. It can also affect other areas like your eyebrows, behind the ears, and around the nose.

Treatment Tips:

Use shampoos with active ingredients like ketoconazole, salicylic acid, or zinc pyrithione.

If symptoms persist for more than two weeks, consult a dermatologist for personalized care.
